EPSON Stylus PHOTO 2100/2200 2.2.4.3 Paper Mode Setting The paper mode that matches the print medium is selected according to the statuses of the PE sensor, CD-R sensor (Only for Stylus PHOTO 2100) and Release lever (sensor) to determine the paper loading sequence (paper locating control). The following table indicates the relationships between the sensors and paper modes. Table 2-12. Paper Mode Setting Paper Mode PE Sensor CD-R Sensor PG Sensor Release Sensor Roll paper ON OFF ON OFF Board paper ON OFF OFF OFF CD-R (Only for Stylus OFF ON OFF ON PHOTO 2100) Note: Panel switch operations change depending on the selected paper mode.

Revision B ! Wait time Photo-ink (HCD ink: Photo-black, Light-black) is easy to dry, but Matte-ink (PPI ink: Matte-black) is difficult to dry. For the medium that uses Matte-black, therefore, paper is transferred after a maximum of 2 second wait time has elapsed after printing according to paper loading amount conditions. " Waiting conditions 1. When the paper loading instruction is 2672/1440 steps or more, paper loading starts after the wait time. 2. When the paper loading amount is less than 2672/1440 steps, the time taken between paper loading and printing up to the roller is estimated so that the time to reach the roller will be the wait time.
